Target detection and driving behaviour measurements in a driving simulator at mesopic light levels.

During night-time driving hazardous objects often appear at mesopic light levels, which are typically measured using light meters with a spectral sensitivity that is only valid for photopic light levels. In order to develop suitable mesopic models a target detection experiment was performed in a driving simulator. While subjects drove along a winding road they had to respond to randomly presented circular targets at various eccentricities.

Relation between glare and driving performance.

The present study investigated the effects of discomfort glare on driving behavior. Participants (old and young; U. S.
